why following not work: from sys import ps1 ps1 = 'something else ' but does? import sys sys.ps1 = 'something else ' if run simple test import sys sys import ps1 ps1 = 'something else' sys.ps1 = 'something else' the first assignment doesn't work, second does. id() both ps1 , sys.ps1 same, should refer same thing, right? the short version is: assignment doesn't mutate in python, rebinds names. rebinding different name, happens bound reference same string sys.ps1 doesn't affect sys.ps1 in way. let's go through step step: from sys import ps1 this imports sys (but doesn't bind name sys in current globals), binds name ps1 in current globals same object sys 's ps1 . ps1 = 'something else ' this rebinds name ps1 in current globals same object literal 'something else' . there's no way possibly affect sys module. import sys this imports sys , , binds name sys in current glo

i'm new nginx, pardon me if i'm being obtuse. have service sitting behind nginx proxy, , using auth_basic prevent being able hit it. want allow angular app hit service, want control allowed perform particular request methods (get, post, del, options), , using auth_basic doesn't seem best bet, since don't want hardcode login/password js (duh). way can figure out how say: if ($request_method = options) { proxy_pass_header access-control-allow-origin *; proxy_pass_header access-control-allow_methods get, options; etc... } at point, i'd allow , options requests anyone, want restrict post, del locations (such internally, or trusted ip). currently, though, if put proxy_pass_header block, says directive not allowed. i've seen other examples people use add_header inside if block that, i'm confused why isn't working. so first of all, best way of doing things, , if not, have recommendation? if best way of handling things,

at organization, we're moving towards modular software architecture.. we're still in beginning phases, , working on user authentication (ua) module. i'm looking information on best practices in terms of user authentication module. my current notion following: client queries ua module login details ua module checks login details. if valid, ua module creates & stores access token, associating token validated user's unique id. the token sent client. client stores token. whenever client requires authentication, queries ua module token. ua module returns user's unique id if token valid, or returns error code if token invalid. i appreciate criticism on methods. i'm interested in knowing how deal accumulation of tokens. if user chooses log out, token removed. my notion tokens should have expiry dates associated them, , worker process should clean these tokens @ regular interval. right way go things? please comment! reference documents

i trying make application faster. want elements appear when ajax request has succeeded. faster create elements append when request has succeeded, or faster create html element in actual html , insert content in element .html? according jsperf : plain old innerhtml beats .html() (and .html() beats .append() ). however according jsperf : dom beats innerhtml . so, might want documentfragment , specified in dom1 , supported in ie6 (so there no reason not use it). since document fragment in memory , not part of main dom tree, appending children not cause page 'reflow' (computation of element's position , geometry). consequently, using document fragments results in better performance. john resig did nice write-up here , concludes: a method largely ignored in modern web development can provide serious (2-3x) performance improvements dom manipulation. you might want combine of techniques per case want optimize. hope helps!

by autofac, it's easy inject static value currentdate property instances of classes in given assembly: builder.registerapicontrollers(asm).withproperty("currentdate", new datetime(2012, 1, 13)); however, how inject dynamic values e.g. values returned lamda () => { return datetime.now; } currentdate property? sounds use pretty standard property injection, this: builder.registerapicontrollers(asm) .onactivating(e => { e.instance.currentdate = datetime.now; }); note may need cast e.instance of type object. see lifetime events in documentation more info. on second thought, why not put initialization in base class constructor? public datetime currentdate { get; private set; } protected apicontroller() { currentdate = datetime.now; } the current date isn't dependency need di container provide.

i trying generate lfm wave in matlab. using code: samplerate = 1e8; % define sample rate of baseband signal (hz) pulsewidth = 10e-6; % define pulse width (seconds) pulserepititioninterval = 50e-6;% define pulse repetition interval (seconds) bandwidth = 10e6; % bandwidth of pulse (hz) iphase = 0; % initial phase in degrees of icomponent qphase = 90; % initial phase in degrees of qcomponent tvector = 0:1/samplerate:pulsewidth; % vector generate ideal pulse icomponent = chirp(tvector,-bandwidth/2,tvector(end), bandwidth/2,'linear',iphase); qcomponent = chirp(tvector,-bandwidth/2,tvector(end), bandwidth/2,'linear',qphase); iqdata = icomponent + 1i*qcomponent; but pulse specification like: pulse width 50e-6 , number of samples in each pulse 1024 , number of pulses 10. please tell changes make in this, or other new have try...

i have been doing ci few months , got point wanted create own library class on ci. now, problem can't seem instance of ci in order me utilize native resources. i've done this. class myclass{ protected $instance; public function __construct() { $this->$instance = &get_instance(); <-- did (theoretically speaking) } } other things i've tried class myclass{ protected $instance = &get_instance(); <-- reports syntax error on apatana public function __construct() { } } anyone of out there can give me better idea on how instance (initializing 1 point on source code) <-- being said that, wanted instance once , use on over class you can use in way in constructor $this->ci = & get_instance(); can use $this->ci->load->model();

i have custom implementation of image animates. want make multiple copies of instance of class using minimum memory , processor time rendering , copying. how go it? easiest recreate whenever need 1 or there proper or suggested method copying image instances. ask because can't find copy constructor , don't know if .clone() implemented in image. if want take care memory can give actors same image. if change image in way , @ 1 of actors change @ actors it(i did sprite , changed textureregion. monsters looked @ same direction). if have same image whole time can create objects , give same reference 1 image. for example this: public arraylist<actor> generateimageactor(){ arraylist<actor> temp = new arraylist<actor>(); image img = new image(____); for(int = 0; <10; i++){ myactor act = new myactor(img); temp.add(act); } return temp; } the rendertime not effect if refare 1 image or

i have visualforce page has 3 functionalities, hence has 3 'public pagereference' subroutines, called when action happens in page [i.e. button] one of functionalities requires user input [i.e. inputtext], main apex code has variable declaration input: public string userinput { get; set; } since each task not related, when hit button on other 2 functionalities, visualforce error, because inputtext object has no user input, how can prevent happening, another way solve this, how turn off visualforce error messages? can error handling apex, looking @ debug log file, error in visualforce not apex, thanks if don't want fire validation can use immediate = true attribute on commandbutton/commandlink bypass validation. - isn't optimal in opinion if want submit part of page , still fire validation have @ actionregion. should allow wrap particular region action call. best purpose. sorry don't have time post full examples should point in right dire

how implement custom jodatime's datetime serializer/deserializer json? i'm inclined use play framework's json library (2.1.1). there default datetime serializer, uses dt.getmillis instead of .tostring return iso compliant string. writing reads[t] amd writes[t] case classes seems straightforward, can't figure out how same datetime. i use play 2.3.7 , define in companion object implicit reads/writes string pattern: case class user(username:string, birthday:org.joda.time.datetime) object user { implicit val yourjodadatereads = reads.jodadatereads("yyyy-mm-dd't'hh:mm:ss'z'") implicit val yourjodadatewrites = writes.jodadatewrites("yyyy-mm-dd't'hh:mm:ss'z'") implicit val userformat = json.format[user] }

out of curiosity, how call '[.class' function in r directly? i know can do: test <- c(2,4,6) test[2] but possible specify class directly? , if so, how? '[.numeric<-'(test , 2) '[.numeric'(test , 2) i have tried these come error: not find function "[.numeric" [ internal generic , means dispatch occurs in c, , base types (like numeric) don't have s3 methods in r. that's why there's no [.numeric or [<-.numeric . it's not clear want, example, can do test <- 1:3 `[`(test, 2) `[<-`(test, 2, 3)

i found an interesting line of code in jshint's config options. the comment associated option reads tolerate using in non-constructor function. i confused. misunderstanding config option? aren't there lot of cases want use this in non-constructor function? when ever want warned it? this options used tell jshint function invoked valid this parameter. for example: function myrandomfunction() { alert(this.something); } myrandomfunction.call(someobject); if strict mode on, jshint warn myrandomfunction shouldn't using this , since doesn't constructor or member function. if know called this (eg, callback), can add /*jshint validthis: true */ suppress warning.
